Detailed ways

In order to improve the security of wireless network transmission of photographed pictures, an embodiment of the present invention provides a method for picture transmission. In this method, the picture sending terminal needs to authenticate with the wireless network when sending pictures, and after the authentication is passed, the The pictures acquired by the shooting device are transmitted through the wireless network.

Referring to Fig. 1, the method for image transmission provided by the embodiment of the present invention specifically includes:

Step 10: The picture sending terminal sends an authentication request to the wireless transmission network;

The realization of this step can be subdivided into steps S01-S02, specifically as follows:

Step S01: the picture sending terminal sends an application authentication request to the wireless transmission network;

Step S01: When the wireless transmission network receives an application for authentication request, it sends back an authentication interface to the image sending terminal;

Here, the authentication interface includes, but is not limited to: an integrated (PORTAL) interface, and a graphical user interface (GUI) interface.

Step S02: After receiving the authentication interface, the picture sending terminal prompts the user to input authentication information on the authentication interface, and sends the authentication information received from the authentication interface to the wireless transmission network in an authentication request.

Here, the authentication information may include account number and password information registered by the user on the authentication platform, and the like. After receiving the authentication information input by the user, the picture sending terminal sends an authentication request carrying the authentication information to the wireless transmission network.

Step 11: When the wireless transmission network receives the authentication request from the picture sending terminal, it authenticates the picture sending terminal according to the authentication information in the authentication request;

In this step, the wireless transmission network authenticates the picture sending terminal. Specifically, the authentication platform of the wireless transmission network may query the saved terminal registration information. If the registration information of the picture sending terminal is consistent, the authentication is passed, and an authentication pass result is returned to the picture sending terminal; otherwise, the authentication fails, and an authentication failure result is returned to the picture sending terminal.

Step 12: When the picture sending terminal passes the authentication, send the picture acquired from the picture taking device to the picture receiving side through the wireless transmission network.

In this step, when the picture sending terminal receives the authentication passing result returned by the wireless transmission network, it can transmit the picture obtained from the picture taking device through the wireless transmission network.

Wherein, the picture sending terminal reads pictures from the picture taking device through an interface with the picture taking device, and the interface includes a current standard Universal Serial Bus (USB) interface, and various device connection interfaces that may appear in the future.

The picture sending terminal sends the picture to the picture receiving side through the wireless transmission network, which can be subdivided into steps S10-S12, as follows:

Step S10: the picture sending terminal and the picture receiving side perform authority verification;

Here, when specifically performing authority verification, the picture sending terminal first activates the corresponding session connection function, and submits authority information, including account number and password, to the server on the picture receiving side; Authorization verification, and return the verification result to the picture sending terminal.

Step S11: after the authority authentication is passed, the picture sending terminal establishes a connection session with the picture receiving side;

Here, since pictures can be sent in various transmission modes according to user settings, including transmission modes such as File Transfer Protocol (FTP) and Simple Mail Transfer Protocol (SMTP), according to different transmission modes, the established The connection session is also different, the FTP connection session is established by using the FTP transmission mode, and the SMTP connection session is established by the SMTP transmission mode.

Step S12: The picture sending terminal sends the picture to the picture receiving side through the established connection session.

Preferably, before sending the picture to the picture receiving side, the picture sending terminal can also encrypt the picture, and then send the encrypted picture to the picture receiving side. Through image encryption processing, users who have high requirements for information security can be better satisfied, and the security of image transmission is ensured.
